Subject: Fix tigervnc long press issue
|
|
|
|
Using xen tools 'xl vncviewer' with tigervnc (default on SLE-12),
|
|
found that: the display of the guest is unexpected while keep
|
|
pressing a key. We expect the same character multiple times, but
|
|
it prints only one time. This happens on a PV guest in text mode.
|
|
|
|
After debugging, found that tigervnc sends repeated key down events
|
|
in this case, to differentiate from user pressing the same key many
|
|
times. Vnc server only prints the character when it finally receives
|
|
key up event.
|
|
|
|
To solve this issue, this patch tries to add additional key up event
|
|
before the next repeated key down event (if the key is not a control
|
|
key).
